I am stuck on this screen when I type in the URL. Please refer to the attachment - what do I do?
Looks like a connection issue, though I've been playing a bit after that time with no problems.
Try (in order)
1) closing/reopening your browser, then hit CTRL-R on the login page (before you enter your credentials),
2) restart your PC,
3) restart your Router (if possible),
No luck - when I CTRL R it briefly shows the boxes to enter username and password - but then quickly vanishes and goes back to the "sorry connection..." message.
